[m-users.] How to compile with localy installed GC?

[Left Right]

Furthermore, I found this part of configure script:

if test "$GCC" = yes -o "$USING_MICROSOFT_CL_COMPILER" = yes; then
    # Don't add -I/usr/local/include, since it causes a warning
    # with gcc 3.1, and gcc already searches /usr/local/include.
    # Microsoft compilers don't understand Unix pathnames.
    { $as_echo "$as_me:${as_lineno-$LINENO}: result: no" >&5
$as_echo "no" >&6; }
else
    # It's some other compiler.  We don't know if it searches
    # /usr/local/include by default, so add it.
    if test -d /usr/local/include/.; then
        { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5
$as_echo "yes" >&6; }
        ALL_LOCAL_C_INCL_DIRS="-I/usr/local/include "
        ALL_LOCAL_C_INCL_DIR_MMC_OPTS="--c-include-directory
/usr/local/include "
    else
        { $as_echo "$as_me:${as_lineno-$LINENO}: result: no" >&5
$as_echo "no" >&6; }
    fi
fi

which suggests that /usr/loca;/include should be already searched, but
I don't think it is... My GCC version is gcc (GCC) 6.3.1 20170306, on
Arch Linux amd64, can this be related?

Thank you.
